I enjoy both. If I am able to I rather have the original but I tend to move around a lot chasing my toddler so English dub really helps me at least follow the story line even if I am unable to see whats happening. ^_^
Dub is easier for me since I am moving around a lot cleaning house etc. and just listen to the show. Although if I am able to sit and watch the whole thing then I would rather go with the subtitles.
i prefer original ;)
